Fault source
Possible consequences
Flow temperature
> 55°C
Device works inefficiently
Device is constantly malfunctioning
Compressor is heavily
Temperature of the
brine
< -6°C
Device works inefficiently
Danger of freezing of the device
No flow rate for
heating equipment
The system will be extremely
overloaded
released (=high
No flow rate for
brine equipment
The system will be extremely
overloaded until the safety device is
released (=low pressure switch)
In addition, a freeze of the system
and
the
device
exchanger and subsequent escape
of refrigerant can take place.
In the worst case, the device is
destroyed and must be replaced!
No ground water
flow (only for WW-
devices)
The system will be extremely
overloaded until the safety
released (=low pressure switch)
A freezing of the system and the
external heat exchanger is possible.
: Overview of the operation conditions to be maintained
Possible consequences
Measures to avoid faults
Device works inefficiently
Adapt operating temperatures to
the actual requirements and set as
low as possible
Device is constantly malfunctioning
Compressor is heavily overloaded
Device works inefficiently
Danger of freezing of the device
Check brine flow
Possibly air in the device
System pressure is too low
The system will be extremely
overloaded until the safety device is
released (=high pressure switch)
With new systems, daily checking
of the water flow rate is required
(thereafter annually).
